Revolutionizing Cancer: The Role of Horizontal Gene Transfer

This chapter examines innovative research challenging the traditional view of cancer as a strictly clonal disease, presenting evidence for horizontal gene transfer among cancer cells. It explores how cancer cells may acquire DNA from their environment, notably through an infectious form of canine cancer, and discusses the implications for cancer evolution and treatment. Highlighting the fascinating concept of transmissible cancers, the chapter sheds light on the genetic exchanges that contribute to drug resistance and malignancy in tumors.
